ELECTRICAL APPARATUS FOR TREATING DISEASES.

Application led March 5, 1923. Serial No. 622,803.

- To alll whom, 'it may concer-n.:

- providev an e ectrical apparatus by( which Be it known that I, WILLIAM RUNNING, a subject of the King of Great Britain, residing at Detroit, in the county ofVVayne and State of Michigan, have invented certain new and useful Improvements in Electrical Apparatus for- Treating Diseases, of which the following-is a specification, reference being had therein to the accompanying drawings.

The p rimar object of my invention is to assembled in a cabinet having an instrument board, supporting'a majority of the electrical 'instruments on the inner wall thereof with operating .instrumentalities on 4the outer wall of the instrument board so that electrical connections may be easily established and the operation of the apparatus easily regulated. A

\ A further object of vthis invention is to accomplish4 theabove results by a novel arrangement of electrical instruments and de `vices which will be hereinafter specifically described and then' claimed, .and reference will now be had to the drawings, wherein- Figure 1 is a front lelevation of the electrical ap' aratus, partly broken away to show con enser connections;

Fig. l2 is a horizontal sectional view of the same,and

Fig. 4 is a diagrammatic'view of the electrical instruments, ydevices and wiring enteringuintom invention.

I provi e a cabinet or a box-like structure composed of a baseor bottomv wall` 1, end walls 2, arear wall 3, a ,hingedl top wall or lid 4,-and a front wall or instrument board 5. The walls 1 to .4 inclusive may be made of wood and the instrument board 5. of hard rubber or any suitable in sul'ation material. The instrument board 5 is d etachabIy held byscrews 6 or other fastemng means so that'it canbe easily removed should occasion require. f

In the cabinet, parallel to the rear Wall 3 is a partition 7y providing a chamber 8 fora condenser composed of ,grid` frames 9 separated by a partition 10 made of any suitable insulation material, as lfard rubber or fiber and said partition serves as a dielectric for grids .11 and 12 mounted in the frames 9. d

Mounted on the instrumentboard 5, adjacentthe upper edge thereof, are binding posts 13 and 14 for leading-in wires 15. On the outer. wall`of`the instrument board 5 is a holder 16 for a conventional-form of carv tridge fuse 17 and one end of the fuse holder is connected by a wire 18-to the binding post 13.

" Mounted on the inner Wall of the instrument board 5 is a bracket or holder 19 for a spark coil or interrupter which may be in the form ofan electro-magnet 2() provided with a resilient armature 2l adapted to vibrate relative to a contact member 22. The

resilient armature 21 is connected by a wire 23 to a conventional form of switch '24, preferably of the push button type, and -said switch is connected b 'a wire 25 to the binding post 14. The resllient armature 21 is also connected by a wire 26 to a fixed condenser 27 and saidv condenser by a wire 28 to the contact member 22. The purpose of the fixed condenser is to prevent pitting of the contact points of the contact member 22 and the resilient armature 21.

Mounted on the inner or rear wall of the instrument board 5 are transformer coils 29 and 3() and the coil 29 is connected by a wire 31 to one ofthe terminals of the electromagnet 20, while the other terminal of said electro-magnet is connected by a wire 32 to thefuse holder 16.

l The transformer 29 has both of its coils connected by a wire'33 to one of the terminals 3 4 of a spark producing device and the `'other terminal 35 of' said device is connected 'by a wire 36 to the condenser grid 11. One

of the coils of the transformer 29 is'connec-ted by a wire 37 to a'conventional form of ammeter'38 mounted in the instrument board 5, said ammeterbeing connected' by av i milli-ammeter 40, carried by the instrument board and in circuit with the transformer 30. The milli-ammeter 40 is connected by a wire 41 to the condenser grid 12 and by a Wire 42 to one ofthe coils of the transformer 30, the1 other coil being connected by a wire` of vthese binding posts is connected by a wire 48a to an, electrode49a adapted to be applied to av human body 50 for electrical treating purposes. The electrode 49a may be f any desired 'forni and the human body has a grounded connection 47, so that there is a complete secondarycircuit.

One of the electrical vcircuits may be traced from the binding post 14 through the switch'24to the resilient armature 21 and the contact member 22, -by Wire 39 to the ammeter 38, by Wire 37 to the transformer 29, Wire '31- to thefelectro-magnet 20, Wire 32 to the fuse 17, and Wire 18 to the binding post.

-Another circuit may be. traced from the transformer 29 through the spark produc-v ing device including terminals 34 Aand 35, by wire 36 vto the condenser grid 11, then from the'condenser grid 12 by wire 41 to the milli-ammeter 40 and by Wire 42 to the transformer 30. From the transformer through the variable*condenserj 44 to the binding post 46 'and the ground. This last mentioned circuit, may be shunted through a grounded human body'by one or more electrodes attached to the body and connectcd to the binding posts 49 which are electrically connected vto the transformer 30.

The apparatus will permit of tissues' of the human body being subjected to an oscillatory or vibratory electrical current without direct metallic connection with the source of electrical energy, because of the condenser gridsfnterposed between the source of electrical energy and the human body, consequently there is no danger of the human body being shocked or injured by any accil dental excessive current of electricity. It is by virtue of the variable condenser and other electrical devices of the apparatus that the electrical treatment may be varied for different diseases,'and While in the drawings there is illustrated a preferred arrangement of the electrical devices, I desire it to be understood that there may be other arrangements, and such changes as are permissible by the appended claim. i

What I claim is ze An electrical apparatus of the character described', comprising a cabinet having front and rear-,Walls with the front wall formed by an instrument board, a plate of insulation adjacent thel rear Wall of said cabinet,

condenser grids at each side of said plate of insulation, one of said condenser grids being 1n a leg of an osclllatory current circult, a ground c1rcu1t for the other grld, a transformer in each circuit with. the transformer' of the ground circuit adapted to be shunted through a grounded body, an ammeter on the instrument board in the oscillatory current circuit, and a milliammeter on the inl strument board in the ground circuit.

In testimony whereof I ailixvmy signature.

WILLIAM RUNNING.
